Richoux exited the Interstate 12, traveling northbound on Millerville at a high rate of speed in his gray Hyndai Tiburon and, according to a witness, was swerving, sheriff’s department spokesperson Casey Rayborn Hicks said.

It appears Richoux continued to drive at a high rate of speed until striking the base of a signal light pole at the intersection, Hicks said, adding the incident is still under investigation.
